Based on the embodiments of the disclosure, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the disclosure.

In order to package and store a debris collection base 1000 conveniently, an embodiment of the disclosure provides a debris collection base 1000. With reference to FIGS. 1-5 , the debris collection base 1000 is used for cooperation with a cleaning robot 2100. The debris collection base 1000 includes a body 100, a bearing seat module 200, and a fan 300.

The body 100 includes a first splicing end 100 a, a debris collection cavity 100 b spaced apart from the first splicing end 100 a, and a debris collection channel 100 c extending from the first splicing end 100 a to be in communication with the debris collection cavity 100 b.

Both the debris collection channel 100 c and the debris collection cavity 100 b may be formed by cavities on the body 100. The debris collection channel 100 c may also be formed by a pipeline structure mounted on the body 100. The debris collection cavity 100 b may also be formed by a housing container structure or a debris collection bag mounted on the body 100. The specific formation ways of the debris collection channel 100 c and the debris collection cavity 100 b is not specifically limited herein. The debris collection cavity 100 b may store debris, paper scraps, etc. temporarily.

The bearing seat module 200 is used for bearing the cleaning robot 2100. The bearing seat module 200 includes a second splicing end 200 a, a debris collection opening 200 b spaced apart from the second splicing end 200 a, and a debris inlet channel 200 c extending from the second splicing end 200 a to be in communication with the debris collection opening 200 b. The second splicing end 200 a is capable of being spliced with the first splicing end 100 a or separated from the first splicing end 100 a. The debris inlet channel 200 c is in hermetical communication with the debris collection channel 100 c when the first splicing end 100 a is spliced with the second splicing end 200 a, so that debris of the cleaning robot 2100 may be conveyed to the debris collection cavity 100 b through the debris collection opening 200 b, the debris inlet channel 200 c, and the debris collection channel 100 c in sequence.

In an embodiment of the disclosure, the first splicing end 100 a is arranged at a lower portion of a side end of the body 100, and the second splicing end 200 a is arranged at a side end of the bearing seat module 200 correspondingly. In other embodiments, the first splicing end 100 a may also be arranged at a lower end of the body 100 a, and the second splicing end 200 a may also be arranged on an upper surface of the bearing seat module 200 correspondingly.

The debris collection opening 200 b may be of a rectangle, a circle, or a kidney shape, etc., which will not be specifically listed herein. The debris inlet channel 200 c may be formed by a cavity on the bearing seat module 200. The debris inlet channel 200 c may also be formed by a pipeline structure mounted on the bearing seat module 200. The specific formation way of the debris inlet channel 200 c is not specifically limited herein.

The fan 300 is fixedly connected with the body 100. The fan 300 is in pneumatic communication with the debris collection cavity 100 b. The fan 300 is used for driving air to flow, so as to generate negative pressure in the debris collection cavity 100 b, thereby sucking the debris stored in the cleaning robot 2100 into the debris collection cavity 100 b.

The fan 300 may be mounted in the body 100. The fan 300 may also be mounted outside the body 100, which will not be specifically limited herein. There are numerous types of fans 300. The fan may be a centrifugal fan, a negative pressure fan, or a high pressure fan, which will not be specifically limited herein. The fan 300 may drive air to flow from the debris collection opening 200 b to enter the debris collection cavity 100 b, so as to suck the debris stored in the cleaning robot 2100. In other embodiments, the fan 300 may also drive air in the debris collection cavity 100 b to flow towards the debris collection opening 200 b, so as to discharge debris in the debris collection cavity 100 b.

When the cleaning robot 2100 is required to discharge the debris, firstly, the first splicing end 100 a of the body 100 is spliced with the second splicing end 200 a of the bearing seat module 200, so as to assemble the debris collection base 1000 for use. Then the cleaning robot 2100 moves to the debris collection opening 200 b of the bearing seat module 200 or is placed at the debris collection opening 200 b of the bearing seat module 200. Finally, the fan 300 works to drive air to enter the debris collection cavity 100 b from the debris collection opening 200 b, so that dust, paper scraps, etc. in the cleaning robot 2100 are sucked into the debris collection cavity 100 b through the debris collection opening 200 b, the debris inlet channel 200 c, and the debris collection channel 100 c in sequence. Therefore, the cleaning robot 2100 is capable of discharging the debris.

When packaging or storing the debris collection base 1000, firstly, the first splicing end 100 a of the body 100 is separated from the second splicing end 200 a of the bearing seat module 200, and the body 100 and the bearing seat module 200 are maintained separately. Then the body 100 and the bearing seat module 200 are stacked together to be packaged or stored.

According to the technical solution described above, the debris collection base 1000 is divided into the body 100 and the bearing seat module 200 which may be spliced with each other or separated from each other. The bearing seat module 200 serves as a base of a debris collection base 1000 in the prior art, so that a size of the bearing seat module 200 is reduced, so that the bearing seat module 200 does not tend to store retained debris and occupies a small space. Therefore, the debris collection base 1000 is maintained conveniently. Moreover, the debris collection base 1000 is packaged and stored conveniently.

There are numerous ways to splice the first splicing end 100 a with the second splicing end 200 a or separate the first splicing end 100 a from the second splicing end 200 a. With reference to FIG. 1 , in an embodiment of the disclosure, the debris collection base 1000 includes at least one locking member 400. The locking member 400 is arranged at the first splicing end 100 a or the second splicing end 200 a, and the locking member 400 is used for locking or unlocking the first splicing end 100 a and the second splicing end 200 a.

According to the technical solution described above, the first splicing end 100 a and the second splicing end 200 a are locked under an action of the locking member 400. Therefore, the first splicing end 100 a may be spliced with the second splicing end 200 a. The first splicing end 100 a and the second splicing end 200 a are unlocked under the action of the locking member 400. Therefore, the first splicing end 100 a may be separated from the second splicing end 200 a.

In an embodiment of the disclosure, two locking members 400 are provided, and the two locking members 400 are arranged on two sides, opposite each other, of the debris collection base 1000, respectively. Therefore, a connection strength between the first splicing end 100 a and the second splicing end 200 a during splicing may be ensured. In other embodiments, one, three, four, five, six or more locking members 400 may be provided.

There are numerous types of locking members 400 described above. With reference to FIG. 1 , in an embodiment of the disclosure, a surface, close to the first splicing end 100 a, of the body 100 is concavely provided with a first mounting groove 100 f, and a surface, close to the second splicing end 200 a, of the bearing seat module is concavely provided with a second mounting groove 200 e. The first mounting groove 100 f is penetrated at a side adjacent to the bearing seat module, and the second mounting groove 200 e is penetrated at a side adjacent to the body 100, so that the first mounting groove 100 f is in communication with the second mounting groove 200 e.

The locking member 400 includes a first hook 410 and a second hook 420 cooperated with the first hook 410. A portion, away from a hook portion, of the first hook 410 is rotatably mounted in the first mounting groove 100 f through a rotary shaft. Two ends of the rotary shaft are arranged on two inner walls, opposite each other, of the first mounting groove 100 f, respectively. The first hook 410 may cooperate with the second hook 420 or the first hook 410 may not cooperate with the second hook 420 by rotating the first hook 410 forwards or reversely, respectively.

When assembling the debris collection base 1000, firstly, the first splicing end 100 a abuts against the second splicing end 200 a, and then the first hook 410 is rotated forwards until the first hook 410 cooperates with the second hook 420. Therefore, the debris collection base 1000 is assembled. When disassembling the debris collection base 1000, firstly, the first hook 410 is rotated reversely until the first hook 410 does not cooperate with the second hook 420, and then the first splicing end 100 a is separated from the second splicing end 200 a. Therefore, the debris collection base 1000 is disassembled.

In an embodiment of the disclosure, both the first hook 410 and the second hook 420 are elastic hooks, so that the first hook 410 may not cooperate with the second hook 420 conveniently. In addition, when the first hook 410 cooperates with the second hook 420, one side, facing away from the second hook 420, of the first hook 410 is coplanar with a surface of the debris collection base 1000. Therefore, a flatness of the surface of the debris collection base 1000 is ensured. In other embodiments, both the first hook 410 and the second hook 420 may also protrude relative to the surface of the debris collection base 1000.

There are numerous types of locking members 400 described above. With reference to FIG. 6 , in another embodiment of the disclosure, a locking member 400 includes a male buckle 400 a of a plastic plug-in buckle and a female buckle 400 b of the plastic plug-in buckle which cooperates with the male buckle 400 a of the plastic plug-in buckle in an inserted manner.

The male buckle 400 a is mounted on a surface, close to the first splicing end 100 a, of the body 100, and the female buckle 400 b is mounted on a surface, close to the second splicing end 200 a, of the bearing seat module 200. The male buckle 400 a is inserted into the female buckle 400 b when the first splicing end 100 a is spliced with the second splicing end 200 a.

When assembling the debris collection base 1000, the first splicing end 100 a abuts against the second splicing end 200 a to drive the male buckle 400 a to be inserted into the female buckle 400 b. Therefore, the debris collection base 1000 is assembled. When disassembling the debris collection base 1000, the male buckle 400 a is pressed to pull out the male buckle 400 a from the female buckle 400 b, so as to drive the first splicing end 100 a to be separated from the second splicing end 200 a. Therefore, the debris collection base 1000 is disassembled.

In order to enable the debris inlet channel 200 c to be in hermetical communication with the debris collection channel 100 c, with reference to FIGS. 1-5 , the debris collection base 1000 includes an elastic member 500. The elastic member 500 is fixed at one end, away from the debris collection cavity 100 b, of the debris collection channel 100 c, or fixed at one end, away from the debris collection opening 200 b, of the debris inlet channel 200 c. When the locking member 400 locks the first splicing end 100 a and the second splicing end 200 a, the elastic member 500 is elastically compressed between the first splicing end 100 a and the second splicing end 200 a and hermetically connects the debris inlet channel 200 c and the debris collection channel 100 c. Therefore, the debris inlet channel 200 c is in hermetical communication with the debris collection channel 100 c.

The elastic member 500 is arranged as a closed loop. The elastic member 500 itself may be arranged as the closed loop, or the elastic member 500 may be arranged as a closed loop by connecting an elastic strip having a certain width end to end, which will not be specifically limited herein.

One axial end of the elastic member 500 is mounted on a surface of one end, away from the debris collection opening 200 b, of the debris inlet channel 200 c in a peripheral direction of the debris inlet channel 200 c. The other axial end of the elastic member 500 is snap-fitted with the sealing groove 110 c. In other embodiments, a surface of one end, away from the debris collection opening 200 b, of the debris inlet channel 200 c may also be concavely provided with a sealing groove 110 c arranged in a peripheral direction of the debris inlet channel 200 c. One axial end of the elastic member 500 is mounted on a surface of one end, away from the debris collection cavity 100 b, of the debris collection channel 100 c in a peripheral direction of the debris collection channel 100 c. The other axial end of the elastic member 500 is snap-fitted with the sealing groove 110 c.

According to the technical solution described above, when the first splicing end 100 a is spliced with the second splicing end 200 a, the elastic member 500 is elastically compressed between the first splicing end 100 a and the second splicing end 200 a, and one end, away from the debris inlet channel 200 c, of the elastic member 500 is snap-fitted with the sealing groove 110 c. Therefore, a sealing performance of a communication portion between the debris inlet channel 200 c and the debris collection channel 100 c may be enhanced.
